kVAR to MFD Converter
How to Use kvar to mfd Calculator
Follow these simple steps to use the kvar to mfd calculator:
- Enter Reactive Power (kVAR): Input the required reactive power in kilovolt-ampere reactive (kVAR).
- Enter Voltage (V): Provide the system voltage (line voltage for 3-phase or phase voltage for single-phase).
- Enter Frequency (Hz): Input system frequency (usually 50 Hz or 60 Hz).
- Select Phase Type: Choose single-phase or three-phase system.
- Click Calculate: The calculator instantly converts kVAR to capacitance in MFD (microfarads).
Tip: Always double-check voltage and frequency for accurate capacitor sizing.

Formula
For single-phase:
For three-phase:
Where:
- C = Capacitance in microfarads (µF / MFD)
- kVAR = Reactive power
- f = Frequency (Hz)
- V = Voltage (Volts)
Example Calculation
Convert 10 kVAR to MFD at 400V, 50Hz (3-phase system)
1. Write formula:
C = (10 × 109) / (2 × 3.1416 × 50 × 400² × 3)
2. Calculate denominator:
400² = 160,000
2 × 3.1416 × 50 × 160,000 × 3 =
150,796,447 (approx)
3. Final calculation:
C = 10,000,000,000 / 150,796,447
C ≈ 66.3
µF
Result: 10 kVAR ≈ 66.3 MFD at 400V, 50Hz (3-phase)
